Application filed October 27, 1905. Serial No. 284,731.

My invention relates to sample-tablesfor filter-plants, its object being to rovide suitable apparatus by means of w 'ch samples ofthe filtered Water from different filters, the raw water, or treated water may be conducted to a common point and separately exposed side by side to the view of the opera tor for the purposes of comparison or test at any time durin the operation of the plant. 0 these en s my invention comprises, generally stated, a suitable table or platform aving a series of transparent cylindrical or other shaped receptacles with connections thereto from the various filters, the raw-water supply, &c., and means for delivering the water to said receptacles, whereby the condition of the diflerent samples-of waterwill be visible to the eye of the o erator at all times during the operation of t 0 plant.

To enable others skilled in the art to make and use my invention, Iwill describe the same more fully, referring to the accompanying drawings, in which Figure 1 is an end view of my improved sample-table and connections leading to the lifting ap aratus. Fig. 2 is a plan view thereof. on the line 3 3, Fig. 2. Fig. 4 is an enlarged view of one of the water-receptacles, partly in section; and Fig.5 is a cross-section on the line 5 5, Fig. 4.

Located within the filter buildin is the table 2, which may be of any suita le construction,., that shown being formed of woodwith paneled ends and sides. 1 Mounted on the table 2 are a series of .transparent cylinders 3, said cylinders being held between the base-rings 4 and the caps 5. Interposed between the upper and lower ends of the cylinders and the base-pieces 4 and caps 5 are the rubber or other gaskets 6, the parts ofthe cylinder being securely held together by means'of the tie-bolts 7, which pass through the cap-pieces 5 and through the'baseieces 4 to the top 8 of the table 2, said tie-b0 ts be ing provided with the nuts 9 at the lower ends Bay-this construction the cylinders may be rea ig. 3 is an enlarged sectional view.

y removed and taken apart for the pu ose of cleaning or for the renewal of the gas ets 6 when necessar The table-to 8 may be orme'd of marble or other suitab e material provided with. the openings 10, through which pass the pipes 1 1, leading to the corresponding cylinders. The upper ends of the pipes 11 are threaded and screwed into the threaded openings 12 in the base-pieces 4. The gooseneck 13 is threaded into an opening in the cap-piece 5, said gooseneck being provided with the valve 14 and the outlet 15.

The pipes 11, leading to the several cylinders, are connected up with suitable pumps or lifters 16, located down in the pipe-galleries below the floor 17 of the building, said pumps being operated by independent motors or as a multiple pump operated by either water or electric motor. Each of the pum s 16 is provided with an inlet-pipe 18, whic leads directly from the point from which it is desired to convey samples to the which conducts the water passing through said'pumps directly to the cylinder.

' In order to properly designate each cylinder and. its source of supply, brass plates 20,

are secured to the table-to 8 at points opposite each. cylinder, said p ates bearing the number of the filter from which the water is conducted to the cylinder. In the drawings we have illustrated the table as having SIX 0 linders connected up with corresponding ter-beds, the ends 0 linders being connected directly with t e raw and treated water supplyas supplied by the pipes 26 and 27.

Located in openings 28 in the tabletop 8 are the funnels 29, which coincide with the outlets 15' of the oosenecks 13, so that the water discharged om said goosenecks will pass into said funnels. These funnels 29 are connected upwith the pipes 30, which convev the water to the wast en m improved sample-table is in operation an it is desired to test or make comparison of the waters from the different filters, the motors operating the pump 16 are ut' into operation, whereupon the water ii'om the six filter-beds will be conducted up into their respective cylinders 3, whereupon the condition of thewater from the several filters is always visible to the eye of the operator of the plant and he is thus able to readily determine whether the filter-beds are Working uniformly or whether any of them are not working up to the proper point of efficiency. Furthermore, by turning suitable valves he is ableto conduct the raw ortreated water by means of the pipes 26 and 27 to their respective cylinders, so as to compare their condition with that of the filtered water. The waters may be held in the cylinders 3 by closing the valves 14 in the goosenecks 13, or the water may flow continuously through the cylinders 3 by opening the valves 14, whereupon the water is discharged into the funnels 29 and carried off. The name-plates 25 designate the source of supply to the different cylinders, and the operator has always'before him. the

waters particularly designated, so that there is no opportunity for mistakes. It is of course apparent that by the use of independent motors for operating the pum 16 the water may be selected from any desired filter without the necessity of Working all the cylinders ofthe table at one time.

By my improvement I provide. a very convenient and simple form of sample-table by means of which the Waters are always'visible to the eye of. the operator for purposes ofcomparison and the necessity of an operator climbing down into the congested pipe-galleries for the purpose of viewing the condition of the water is avoided, and it has been fo'und in practice that owing to this inconvenience the tendency of the operator was to neglect this duty of inspection.

By the use of the gooseneck connection it is possible to obtain samples of the waters for analysis, if desired.

What I claim is- 1. Apparatus of the character described, comprising a suitable table, or platform, a

series of transparent-receptacles thereon, and connections from different filter-beds, the raw-water supply, &c.-, to said receptacles.

2. Apparatus of the character described comprising a suitable table, or platform, a

'series of transparent rece tacles thereon,

connections from different fi ter-beds to said receptacles, and means for forcing the water into said receptacles. p

3. Apparatus of the character described comprising a suitable table, or platform, a series of transparent receptacles thereon, connections from different sources of watersupply to said receptacles, and means for carrying away the contents from said receptacles.

4. Apparatus of the character described comprising a suitable table, or platform, a

series of transparent receptacles thereon,

connections from different sources of water-. supply leading'to said receptacles, and nameplates on said table designating the source of su ply and'located opposite each receptacle.

n testimony whereof I, the said FREDER- ICK B. LEoPoLn, have hereunto set my hand.
